What is it?
Plugindoctor fills a longstanding gap in the market: a cross-platform and cross-bitformat plugin analyzer for VST and AU plugins. Whether you are a plugin developer yourself who wants to thoroughly test the audio quality of your latest and greatest product, or a power user who wants to understand in more detail what exactly a specific plugin is doing to your precious audio material, Plugindoctor will help you find out!

1. Highest quality, double precision FFT engine, independent stereo channel analysis
2. Linear analysis: magnitude and phase response using delta or random input signal
3. Harmonic analysis: highly accurate frequency response analysis to a sinusoidal input signal. Input strength and frequency can be varied for THD/THD+N calculation. Switchable intermodular distortion modus. Sweep function for fundamental and THD response.
4. Oscilloscope: watch what happens to a sinusoidal input signal in real time.
5. Dynamics: use a ramping signal to test compression or expansion, or an attack-release signal to check your compressor’s attack and decay curves.
6. Performance: how many milliseconds are really spent in your plugin’s audio processing callback (as a function of buffer size)
7. Ability to load two plugins in parallel for simultaneous analysis
8. Freely resizable user interface
9. Three quality settings, corresponding to three different FFT buffer sizes
10. Storage option of curves in Linear and Harmonic analysis mode for easy comparison of settings or of different plugins
11. Built-in screenshot function
12. Standalone version: comes as a 32 and a 64 bit executable
13. Plugin version: available in VST/VST3/AU/AAX format for parallel analyzing and listening in your DAW
14. Can load VST, VST3 and (on Mac) AU effect plugins

If you’ve been looking for an all-encompassing plugin analyzer, this is it. A free demo is available, with an occasional processing interruption and a limitation of one plugin per session.
